Foci in math
WebThe given focus of the parabola is (a, 0) = (4, 0)., and a = 4. For the parabola having the x-axis as the axis and the origin as the vertex, the equation of the parabola is y 2 = 4ax. Hence the equation of the parabola is y 2 = 4 (4)x, or y 2 = 16x. Therefore, the equation of the parabola is y 2 = 16x. Example 2: Find the focus of the parabola ...

WebThe vertices are (±a, 0) and the foci (±c, 0). Define b by the equations c 2 = a 2 − b 2 for an ellipse and c 2 = a 2 + b 2 for a hyperbola. For a circle, c = 0 so a 2 = b 2. For the parabola, the standard form has the focus on the x-axis at the point (a, 0) and the directrix is the line with equation x = −a.
